These brushes glass between the brushes 13 and .14 and the reciprocating of the spindle 15 cours in one continuous downward movement of the glass held in the hands of the operative. At the bottom of its stroke the pressure on the spindle 15 is released. The compressed spring 23 then reverses the direction of movement of the spindle to return it to its original normal position. Durin the resturn of the spindle to normal position the brushes 13 and 14 rotate on the glass to complete the cleaning thereof. As

shown in Fig. 2, the frusto-conical spring 23 does not flatten into a single plane, but retains its frusto-conical formation at the limit of downward movement of the spindle 15. \Vith this construction the spring 23 acts as a thrust bearing for the spindle 15 to insure the rotation and reciprocation of the spindle 15 in the nut 18 without binding.

It will be clear to those skilled in the art, and with the general objects of the present invention in view, that changes may be made in the details of construction, the described and illustrated embodiment thereof being intended as an exploitation of its underlying essentials, the features whereof are definitely stated in their true scope in the claims hereto appended.

WVhat is claimed as new, is:

1. In an apparatus for cleaning glassware used in dispensing food and beverages, a support, a cylindrical wall projecting vertically from the support, a casing secured to the exterior of the wall, a stationary nut secured to the casing, a brush supporting spindle mounted for rotation and longitudinal reciprocation in the nut, a collar secured to the spindle, and a frusto-conical spring having its larger base engaged with the support within the cylindrical wall and its -'smaller base engaged with the collar.

2. In an apparatus for cleaning glassware used in dispensing food and beverages, a plinth adapted to engage with the bottom of a tank, an open column integrally connected to the plinth and provided with external threads, a frusto-conical casing provided with internal threads on its larger base engaged with the threads on the column, a stationary nut secured to the casing, a brush supporting spindle mounted for rotation and longitudinal reciprocation in the nut, a collar secured to the spindle, and a frusto-conical spring having its larger base engaged with the plinth within the column and its smaller base engaged with the collar.

-In testimony whereof I have signed my name to this specification.
